ADJUSTABLE THIRD OR FOURTH POINT SUPPORT FOR BRAKE-BEAMS.

Application filed May 27,

T 0 all whom it may concern.

Be it known that I, CHARLES HAlNns WILLIAMS, a citizen of the UnitedStates, residing at Chicago, :Illinois, have invented a certain. new anduseful Improvement in Adjustable Third or Fourth Point Supports forBrake-Beams,of which the following is a full, clear, and exactdescription, such as will enable others skilled inthe art to whichitappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a side elevational view of one form of my improvedadjustable third or fourth point support for brake beams.

Fig. 2 is a similar view of a modified form.

Fig. 3 is a vertical sectional view on line 3-3 of Fig. 2.

Fig. 4 is a vertical sectional view on the line 44 of Fig. 2.

Fig. 5 is a side elevational view of another modified form of adjustablebrake beam suport.

p This invention relates to a new and useful improvement in adjustablethird or fourth point supports for brake beams, the object being tovertically adjust and adapt the track or support on which the chairmember carried by the beam slides to different heights and therebyaccommodate the beam to different diameters of wheels and to differentmakes of trucks.

The present application is a continuation in part of an applicationfiled by me June 6, 1919, Serial No. 302, 225, (patented September 14,1920, No. 1,352,570,) and involves specifically the use of a hinge forthe supporting track at or near the outer ends of the safety bar for thebrake beam with means for adjusting said hinged supporting trackarranged on the safety bar.

In the drawings, 1 indicates the spring plank, 2 the compression memberof a brake beam, 3 the tension member thereof, 4 the strut and 5 thebrake head. Thisbrake beam is shown as having a supporting chair ormember 6 in the form of a third point support, but it is obvious that mypresent invention is as readily adaptable to fourth point supports.

The purpose of this supporting chair 6 operating on the inclined trackis to guide the brake beam so that the brake shoe will Specification ofLetters Patent. Patented J 11118 14, 1921 1920. Serial No. 384,592.

be (properly applied to the tread of the wheel an be uniformly worn, asis well known in devices of this kind.

is a safety bar preferably sufficiently rigid so as to support and holdthe brake beam in the event that the sustaining devices thereof aredisabled. V

In Fig. 1, the ends of this safety bar are bent downwardly so as to formthe eyes of a hinge to match with complementary eyes of a hinge on ayielding supporting track 8, being preferably made of spring steel. 9 isthe hinge pintle. The track 8 is bent so as to have a vertical portionparallel to the vertical bent portion of the safety bar, these twovertically disposed portions of thetrack and safety bar, respectivelyproviding seats for an adjusting bolt 10 having a nut whereby the trackmember may be adjusted vertically with respect to the safety bar and theangle of its inclined portion thereby prhanged, as indicated in dottedlines in n Fig. 2 I have shown a spring plank 11 having a rigid safetybar 12 secured thereunder in the ends of which safety bar are mountedthreaded rods 13 having guiding eyes at their upper ends, as shown inFig. 3. The vertical position of these eyes may be adjusted by means ofnuts 14 arranged above and below the horizontal flange of the rigidsafety bar.

15 indicates a U-shaped member, one leg of which forms a pintle for theeye 16 of the track support 17. The other leg of this U-shaped member 15passes through the vertical flange of the rigid safety bar. There is aplate 18 forming a seat for nuts 19 by which the member 15 may besecured in position. Adjustment of the angle of inclination of theyielding supporting track 17 may be effected by turning the nuts 14, orthe height of the guiding eye at the upper end of the rod 13, throughwhich the supporting track 17 passes, may be left unchanged and theinner end of the supporting track 17 adjusted inwardly and outwardly bypositioning the lower leg of member 15, in one of the holes 20 of whichthere are a series in the vertical flange of the rigid supporting bar.

In Fig. 5 I have shown a rigid supporting bar 21 mounted under a springplank 22, the inclined track supports 23 in this case being rigid andhinged at their inner ends to the outer ends of the rigid safety bar bymeans of leaf hinges 24:.

In the horizontal flanges of the rigid safety bar and the inclined tracksupports are openings through which pass the threaded ends of U-shapedrods 25. Nuts 26 on the threaded ends of these rods, by impingingagainst the upper and lower faces 0 the horizontal flanges of the rigidsafety bar and inclined track supports enable the outer ends of thelatter to be adjusted, thereby changing the angle of inclination of saidtrack supports.

The forms shown in Figs. 2 and 3 involve dual means of adjustment,consequently the range of adjustment with respect to the inclination ofthe track supports is thus correspondingly increased.

What I claim is: I

1. The combination of a truck spring plank, a safety bar member securedthereto, an inclined third or fourth point supporting track for brakebeams hinged at the end of track for brake beams hinged at the end of fsaid safety bar, and dual means cooperating with the safety bar and thesupporting track for adjusting the vertical height and angle ofinclination of the latter.

3. The combination of a sprin plank, a safety bar secured thereto, aninclined supporting track for the third or fourth point support of abrake beam, which track is hinged to said safety bar at its end, and athreaded element provided with a nut for effecting a vertical adjustmentof the supporting track.

In testimony whereof I hereunto aflix my signature this 19th day of May,1920. 7

CHARLES HAINES WILLIAMS.
